Dear Anuj sir and kunal sir,
first of all sorry.... there was some mis-understanding on my part yesterday.. i was thinking/applying all provisions of sec. 170... thinking that the query is in regards to "succession in case other than death"... which was not right... as u asked query pertaining to death of predecessor... sorry again..
and as said by mr. kunal in his first comment (though he also mis-understood later on)... that the dep. is charged by predecessor/deceased for the whole year and then, his successor will claim dep. for the remain. part of the year... was right... in other words, combining both the dep. claimants, the depreciation amount will be 100% dep. (in aggregate) because u/s 32 it was prescribed for sec. 170 only that it will be allocated on the basis of no. of days between both... but this is not the case of sec. 170...
now, i also think that Mr. A will transfer/sale the asset... and no need to show it as gift.. as it is succession and its transfer by will... so, exempt u/s 47... by the amount of any capital gains arises... and Mr. B will show the amount of asset acquired as that of the previous owner u/s 49(1)... e.g. Mr. A acquired it on Rs. 50000... and t/f on will... thus, Mr. B will also show it at Rs. 50000 (irrespective of the FMV/the amount of will etc...)
Thus, dep. for Mr. A would be Nil.. as he has entered the sale amount (acc. to will) in the column "consideration or other realization during the p.y. out of 3 or 4".... and Mr. B will claim Dep. accordingly, i.e. 50% or 100% depending upon the date of will/transfer of the asset legally...
Best Regards,
